To all whom it may concern:

Be it known that I, JonN GAszPnR, a citizen oi the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have lnvented'certainnew and useful Improvements in Block- Signaling Systems for Railways, and do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to .block signaling systems for railways,

and the invention conl sists in the construction andcombination of as hereinafter shown parts, substantially particularly pointed out in the lllOl'e vla-im.

The object of the invention is to provide signaling' means arranged along the line of the railway at predetermined distances apart and adapted to be automatically operated by moving trains, and wherewith when' one train is4 within a certain block on the line, that its location is definitely known by the signalin device atl opposite ends of the block. l

A further obj ect is to provide theconstrnc tion whereby the signaling devices are caused to repeat signaling movements during the passage of the train over the contact devices along the rails, and for the entire period covcred by the passage ofthe train at this point.

In the accompanying drawings, Figure 1 is a side and sectional view of a complete block in a railway system, and Fig. 2Y is a similar view of the same parts in another Aposition. y.

Thesystem comprises sets of signaling devices A mounted upon posts or uprlghts -2- at predetermined oints along the railway track B, and the signaling devices com rise amp on t e top of posts -2f. shown as mountedupoii the support -3- and it will be understood that any suitable semaphore arm or like member may be combined with the lamp and operatively engaged or mounted upon support 3. The respective lamp supports -3- are placed at suc tive able, sav 4one-half mile between them, and

Athe signaling devices at the end of each block are operatively connected by means of a cable or' other suitable connection `6?-, so that when one is operative, the other is also operative in like measure.

i rela# dlstances apart as may be deemed advis scribed, and in the passage of l The means for operatingr the signaling devices consist of a pan' `f vertically mov- 'able contact members -7 and '-8- respectively for each device, 'and each member is pivotally connected to -9- which is provided with a counterweight -l0- to normally keep one of said members in raised position, so as to be engaged by the wheels of the train. To this end, the said members are either mounted at the side of the rail, or form a movable part thereof. A flexible or other suitable connection -11 running over sheaves or suitable supports 12-, connects with rock member -Sf-e and passes to the rocking o r oscillating support' -3- of the signaling device and preferably through hollow post '-2- and conduitd` pipes (not shown); Each contact member -8- has a curved link its lower end and this link rests u bottom of box -15- and projects neath the other contact member 7 in the same box, whereby when member -8- is depressed by the wheel W of a passin car the other member -7- is raised, an vice versa. However, the rock member -9- a rock member 75 *14* pivotally connected thereto at n the' and counterweight 10- of each contact f member -8-' is arranged to immediately raise the same when the of contact therewith, whereas contact member -7 has its counterweighted rock member arranged to rest upon opposite sides of its center of gravity whereby said member *7- will remain eitherraised or lowered dependent upon the passing-of a wheel either over it or the other contact members' -8-. Each signaling device A is similarly equipped with operating means, such as dethe train into or 'out of the block one and then the' other 'of said members -7- and 8f res ecwheel has passed out vet tively are operated and alternately raisedl and depressed to impart a vibratory movement to the sets of lamps 5- at each end of the block. Thus a train entering a block gives vibratory or flashing indication t0 an-` other train approaching the block from the other end that the block is being occupied, and the devices are so arranged that when the train is within. the block, the signaling devices A are in raised and visible position to indicate'the fact, although stationary not under vibratory movement. However, when the train passes out of the block the last contact member to' be engaged sets the signaling devices so that they will drop out connections with the said devices whereby a o view 1n the casing 5 at each end of continuous vbratory and tiashne, Signal is the block, thus showing that the block is produced by trains entering thebiock und a 15 not ocupied and free to be entered with continuous visible signal 1s obtained when the train is within the block.

In testimony whereof I sign this specication in the presence of two witnesses.
